Lecture Thomas Hertog - On the origin of time.

Together with Helios colleague Walter we went for the first time to Tabloo in Dessel; which is in the backyard of the Graspop Metal Festival area. This rather new visitor center is the visitor and meeting centre in dessel about radioactivity, radioactive waste management and research into nuclear applications. Thomas Hertog took us on a whirling space journey. In between the black holes and the cosmic holograms, he also tells about his special friendship with Stephen Hawking, with whom he worked on an innovative theory about the origin of the universe.

Helium D3 Line with Sol'Ex

Imaging the Sun in HeI D3 line with Sol'Ex Pro. Editing using JSolex and CS4.




Saturn Tilting Ring


The image shows how the rings of Saturn are closing. It also shows my imaging skills.

Sun September 21, 2024 CaIIK, H-alpha, H-beta and FeI(c)

Imaging the Sun with my Sol'Ex pro. It's getting better and better. The sawtooth is almost gone with the use of my EQ8 mount. Some images have it slightly but was due to seeing conditions. Not only is the Sol'ex more robust, finding the different spectrallines is also getting faster: H-alfa, beta, gamma, delta, epsilon, CaIIH and K, Sodium (Na D1 & D2), Helium D3, MgI b1, b2, b4, FeI(c). 

Setting: Sol'Ex pro on TLAPO60/360 and ASI290MM
Filter : Herschel Wedge
Software: SharpCap, Inti, CS4









Saturn Stack with IR742nm filter

Imaging Saturn with TAL200K f/8.5 with barlow x2 and ADC. This brings effective focal point to f/25.68. This time I used a bandpass filter IR742nm. The result was stacked with image taken with IR/UV blocker. The result shows much more details.

Setting:
Scope: TAL200K @f/25, ASI224MC on EQ8
Camera: ASI224MC
ADC, IR/UV blocker, IR742nm
Software: SharpCap4, AstroSurface, Winjupos, Stellarium, CS4

Sun September 20, 2024 Flare AR3831

Imaging the sun with Sol'Ex on sept 20, 2024. By accident a flare was observed in AR3831 but only in H-Beta and CaII H and CaII K.

Setting: Sol'Ex Pro, TLAPO60/360 with ASI290MM
Herschel Wedge
Mount EQ8: sawtooth almost gone compared with my EQ6
Software : SharpCap4, Inti, CS4
